# Notes
- Location of `user://`: `~/.local/share/godot/app_userdata/`.

# ToDo
- [x] Datepicker: On click (without drag) reset velocity to 0; show and focus 'input' to allow introducing value.
- [x] Selecting last (year?)/month/day and de-selecting it, moves value to next;
- [x] Solve how entries are shared across db_screen and stage_screen;
- [x] Remove db_entry;
- [x] Rename db script/node to database;
- [x] scrolling down on the database screen jumps to the end of the list immediatelly;
- [x] edited entry does not show updated once saved;
- [x] edited entry shows updated when selected then press back button;
- [x] load/store database CSV file;
- [x] export database to CSV file;
- [x] allow to reset database;
- [x] split touch logic from database (create TouchItemList);
- [x] split touch logic from stage (create TouchVerticalContainer);
- [x] load/store filters JSON file;
- [x] import/export filters to CSV file;
- [x] add option_sets buttons on stage screen:
    - should show a pop-up with multiple options filtered according to current filters;
    - allow options to be scrolled by dragging;
    - selecting option puts that text on the associated LineEdit;
- [x] add pop-up asking if changes are to be discarded once the stage screen's discard button is pressed;
- [x] add pop-up confirming delete-entry action;
- [x] edit and delete action buttons should be faded-out when no entry is selected;
- [x] Sort option sets alphabetically;
- [x] Check and request file access permissions on Android:
    ```py
    if OS.get_name() == "Android":
		var has_permissions := false
		while not has_permissions:
			var permissions := Array(OS.get_granted_permissions())
			if not permissions.has("android.permission.READ_EXTERNAL_STORAGE") \
				or not permissions.has("android.permission.WRITE_EXTERNAL_STORAGE"):
				OS.request_permissions()
	#			await get_tree().create_timer(1).timeout
				yield(get_tree().create_timer(1), "timeout") # - for Godot 3 branch
			else:
				has_permissions = true
    ```
- [x] Fix the show option sets buttons; they are drawn over the input fields and hide inserted text;
- [x] The stage control must be set to ignore the mouse, otherwise the touch-sensor conflicts with the built-in scroll;
- [x] On database, selecting an entry and removing it will leave the action buttons visible while no entry is selected;
- [x] Tweak 'POINTER_VELOCITY_DECAYING_FACTOR' and 'POINTER_VELOCITY_BOOST_FACTOR' on database and stage screens;
- [x] Allow to parse option sets from database file;
- [x] Check if import_option_sets, store_option_sets, store_database require the parameter save_changes; this requires changes on databse, stage and menu scripts;
- [ ] Fix back button:
    - on stage screen should show pop-up asking it changes are to be discarded;
    - on file-pickers screen should close them;
    - on about screen should close it;
    - on auto-fill pop-up, should close it;
    - on database screen, should deselect selected item, otherwise should quit the app;
- [ ] Hide dialogs title bar (appear in the top with 1 or 2 pixels height);
- [ ] Database menu and action buttons are not nice; Improve appearance;
- [ ] Improve menu appearance;
- [ ] Setup two themes:
    - [ ] theme_light
    - [ ] theme_dark
    - [ ] main/screen_controller is responsible for whos currently on focus, fade animations, input access (enable/disable), and back_key_notification handling.
    For input use:
        node.set_process_input(!pause)
        node.set_process_unhandled_input(!pause)
        node.set_process_unhandled_key_input(!pause)
- [ ] Share DB:
    - share db via html email with db inserted in encoded downliadable field;
